I think the first half of book 4 dipped a bit in quality due to some weaker characters, but the bonkers second half more than made up for it (and the TV version improved on that particular book, IMO).
The show ends on book 6, which means you miss out on pretty much the entire third act of the series. I’d say it’s worth finishing just to get some closure on some of the unresolved loose ends.
